Count values in multidimensional array

[LibraryCode]

Hi,i have the following code,how can i count values -averages per row and column from this code:

 <?php
$data = array( 
               array(""=>"January", "ATL"=>rand(0,335) , "ORD"=>rand(0,335),"LAX"=>rand(0,335),"DFW"=>rand(0,335),"DEN"=>rand(0,335),"JFK"=>rand(0,335),"SFO"=>rand(0,335),"CLT"=>rand(0,335),"LAS"=>rand(0,335),"PHX"=>rand(0,335)),
               array(""=>"February", "ATL"=>rand(0,335) , "ORD"=>rand(0,335),"LAX"=>rand(0,335),"DFW"=>rand(0,335),"DEN"=>rand(0,335),"JFK"=>rand(0,335),"SFO"=>rand(0,335),"CLT"=>rand(0,335),"LAS"=>rand(0,335),"PHX"=>rand(0,335)),
               array(""=>"March", "ATL"=>rand(0,335) , "ORD"=>rand(0,335),"LAX"=>rand(0,335),"DFW"=>rand(0,335),"DEN"=>rand(0,335),"JFK"=>rand(0,335),"SFO"=>rand(0,335),"CLT"=>rand(0,335),"LAS"=>rand(0,335),"PHX"=>rand(0,335)),
               array(""=>"April", "ATL"=>rand(0,335) , "ORD"=>rand(0,335),"LAX"=>rand(0,335),"DFW"=>rand(0,335),"DEN"=>rand(0,335),"JFK"=>rand(0,335),"SFO"=>rand(0,335),"CLT"=>rand(0,335),"LAS"=>rand(0,335),"PHX"=>rand(0,335)),
               array(""=>"May", "ATL"=>rand(0,335) , "ORD"=>rand(0,335),"LAX"=>rand(0,335),"DFW"=>rand(0,335),"DEN"=>rand(0,335),"JFK"=>rand(0,335),"SFO"=>rand(0,335),"CLT"=>rand(0,335),"LAS"=>rand(0,335),"PHX"=>rand(0,335)),

What exactly do you want to count?

[LibraryCode]

I would like to compute average per month (per raw) and columns average

[pritaeas]

Just add an array keeping the sum of all your columns. Add the values inside the loop, divide and display after the loop.

[diafol]

WHy have you got a blank key for months?

[LibraryCode]

RE: To diafol

that field is blank,a nd monyhs ander in column,but i can put month in the field.The problem is the nestred arrays my weak point,i need to see exmple,to understand logic. I have seen example online,but,not with the array like this.

You're probably better off with a simpler array structure:

$data = [
    'January'=> 
               [ "ATL"=>rand(0,335) , "ORD"=>rand(0,335),"LAX"=>rand(0,335),"DFW"=>rand(0,335),"DEN"=>rand(0,335),"JFK"=>rand(0,335),"SFO"=>rand(0,335),"CLT"=>rand(0,335),"LAS"=>rand(0,335),"PHX"=>rand(0,335)],
   'February' =>
               ["ATL"=>rand(0,335) , "ORD"=>rand(0,335),"LAX"=>rand(0,335),"DFW"=>rand(0,335),"DEN"=>rand(0,335),"JFK"=>rand(0,335),"SFO"=>rand(0,335),"CLT"=>rand(0,335),"LAS"=>rand(0,335),"PHX"=>rand(0,335)],
...etc...
];

Alternatively, you can get rid of the month entirely, as arrays should be indexed 0-11 (Jan-Dec) :

$data = [
    [ "ATL"=>rand(0,335) , "ORD"=>rand(0,335),"LAX"=>rand(0,335),"DFW"=>rand(0,335),"DEN"=>rand(0,335),"JFK"=>rand(0,335),"SFO"=>rand(0,335),"CLT"=>rand(0,335),"LAS"=>rand(0,335),"PHX"=>rand(0,335)],
   ["ATL"=>rand(0,335) , "ORD"=>rand(0,335),"LAX"=>rand(0,335),"DFW"=>rand(0,335),"DEN"=>rand(0,335),"JFK"=>rand(0,335),"SFO"=>rand(0,335),"CLT"=>rand(0,335),"LAS"=>rand(0,335),"PHX"=>rand(0,335)],
...etc...
];
